Once the flash verification cycle completes and the standby card returns to an active synchronization status, initiate a manual switchover command to transfer the active link load, then update the second module.\u003c\/p\u003e\n\u003cp\u003eQ: Can an individual SE4101 card be extracted or inserted into the carrier slot while the DeltaV bus is energized?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The electronic subassembly features online insertion and removal (OIR) capabilities, permitting hot-swap maintenance under live system power without disrupting the adjacent communication bus.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Continuity:\u003c\/strong\u003e Bond all external Ethernet network cables using high-quality industrial shielded twisted pair (STP) lines.
